Ash trees are a deciduous tree with compound leaves in opposite pairs having 5-11 leaflets. All leaflets are roughly the same size with exception of the somewhat larger terminal leaflet. They are relatively fast growing, and can grow to be large (up to 100') with a straight trunk extending well into the crown. Ash tree bark is light gray to brown with a diamond like pattern. The wood itself is heavy, strong, hard and straight grain with a light brown color.

* Common Trees in Michigan
Leaves Deciduous, in opposite pairs, pinnately compound; composed of 5-11 leaflets. All about the same size or terminal one larger
Buds Terminal bud broadly pyramidal; 1-3 pairs of scales, with a soft granular surface. Leaf scars oval to semicircular or crescent shaped with many small vein scars
Twigs Stout, straight often flattened beside the leaf scars. In the mature trees, most shoot growth preformed in a bud, in vigorous saplings, summer shoot growth often neoformed.
Flowers Small, dark, borne in compact, many-flowered clusters, arranged laterally on twig, rarely at tip. Pollen flowers and seed flowers on the same or separate trees. Flowers of native species lack petals. The sepals are minute or missing. Appear in early spring before the leaves
Fruits Winged, dry 1-seeded in most species, base encircled by remnants of the flower, borne in large drooping lateral clusters. Mature in autumn, remain on the tree during the winter {blue ash sheds sooner}. Dispersed by wind and water.
Seeds Remain within the fruit; can be stored dry in sealed containers for several years. Require exposure to cool moist conditions for some months before germination.
Bark Varies from finely furrowed with firm ridges to scaly and so soft that it rubs off easily with hand pressure
Wood Medium weight, strength and hardness; tough, shock-resistant, straight-grained, attractive tangential grain-pattern, grayish-brown. Ring-porous; rays inconspicuous
Emerald Ash Borer hatching from d-shaped exit holes
